Abstract(cid:1) The genusMetanomeuta Meyrick is reviewed in the present paper. The type species M. fulvicrinis is redescribed with a
discussion onitsmorphological variations. Twonew species, M. yuexiensis sp. nov. and M. spinisparsula sp. nov. are described
fromChina. Imagesof theadultsand the genitalia are provided. Keys to distinguish the three described species are given, anda
distributionmapisincluded.
